Filter by:An Open-Label, Single-Center, Prospective, Observational, Clinical Use Study Evaluating the Safety and Performance Characteristics of Ephemeral® Tattoo Ink in Healthy Subjects
Consenting subjects will receive a semi-permanent tattoo in place of the standard of care permanent tattoo for radiation marking at the time of the radiation planning scan. Subjects will be monitored to ensure alignment is the same with the semi-permanent tattoo as the current standard of care. Subjects will be monitored to ensure there are no skin reactions or other side effects. Subjects will be followed for 15 months and will send pictures to the treatment team to ensure that the tattoo fades away within 12 months as expected.
The primary aim of this prospective, multicentre study is to determine whether the involved node can be marked using black carbon dye and successfully identified at the time of surgery. The secondary aims are to determine the concordance between the tattooed node and sentinel node, migration of black dye into other nodes, and false-negative rate of tattooed node (in patients undergoing ALND after NACT).
This study will evaluate the use of the Lutronic PicoPlus for treatment of dermatological conditions such as unwanted tattoos and benign pigmented lesions.
The investigators developed an ultra-speed picosecond laser (20ps) with a 20gHz repetition rate that provide very promising results in vitro and in ex vivo skin to remove skin tattoos. The aim of this study is to evaluate the efficacy and tolerance of a new ultra-speed picosecond laser and to compare it to a nanosecond laser for treating black tattoos. In a first phase of the study 10 patients with black tattoos will be treated with increasing fluencies of the picosecond laser to the optimal parameters in terms of efficacy and tolerance. In a second phase, 10 additional subjects with black tattoos will be treated after central randomization on half of the tattoo with the picosecond laser (with the parameters determined in the first phase) and the other half treated with a nanosecond laser.
This is an open-label, multi-center study. Subjects in this study will receive up to eight (8) treatments in 11±5 weeks (6-16 weeks) interval, with the PicoWayTM device using the 1064 nm/ 785±20 nm/ 532 nm handpiece according to the study protocol (tattoo colors). Subjects will return for one follow‐up (FU) visit at the clinic at 8 weeks following the last treatment. Methodology described in the protocol to evaluate efficacy and safety of treatments will be carried out at each visit at the clinic
